IMPROVEMENT IN GAGE-SQCKS.

Specification forming part of Lettere Patent N'o. 192,145, dated June19, 1877 application filled February 3, 1877.

To all whom it may concern Be it known that I, HENRY LEE BOEDEN, ofElgin, in the county of Kane and State of Illinois, have invented a newand Improved Gage-Cock, of which the following is a specication:

body of the gage-cock. The vinternal threadv and the thread of thespindle extend from the valve outward beyond the exterior of the boiler.A passage is provided in the body of the gage-cock for the escape ofsteam or water, which is closed by the valve.

The object of the invention is to provide a gage-cock that will notallow of the escape of hot water or steam if it should be broken offoutside of the boiler-shell.

In the drawing, A is the body of the gagecock, which is boredlongitudinally through its center, and threaded internally to receivethe spindle B, upon which a thread is cut that fits the internal threadsof the body A. The inner end a of the body is concaved to receive theconvex valve C, which is attached to the end ot' the threaded portion ofthe spinv dle B. The outer end of the spindle B is provided With ahand-wheel, D, and is surrounded by a stalling-box, E, at the outer endof the body A.

A passage, b, runs lengthwise through the body A, the inner end of whichterminates at the annular groove d cut in the valve-seat, and is closedby the valve C, and its outer end terminates in a nozzle, c. The body Ais threaded externally and screwed into the boiler in the usual way.

The internal thread of the body A and the thread of the spindle B extendfrom the valve and valve-seat outward beyond the boilershell, so that ifthe gage-cock should by acci-4 dent become broken outside of theboiler-shell the valve would be undisturbed, and the accidents thatusually follow the breaking of a gage-cock entirely avoided.

The valve of the cock is opened or closed by turning the screw by meansof the handwheel. l The stuffing-box at the outer end of the body A isnot deemed essential, as little, if any, water or steam can escapearound the spindle.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- A gage-cock for steam-boilers consisting of a body,A, bored longitudinally and threaded internally, and provided with thepassage b and valve-seat, as described,.a threaded spindle, B, thatextends through the body, and a valve, C, attached to the inner end ofthe said spindle, substantially as herein set forth.
